MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 223,414, dated January 6, 1,880..

` Application led December l0, 1879.

To all whom it may concern:

Be it known that I, WILLIAM TRABUE, of' Louisville, county of Jefferson, and State of Kentucky, have invented certain new and useful Improvements in Magazine Fire-Arms 5 and I do hereby declare the following is a clear, full, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The said invention relates to that class of tire-arms known as magazine bolt-guns, and it has for its chief objects the simplification and increased etciency ot' the devices which operate to bring the successive cartridges from the magazine into position to be exploded, and of the devices by which the shell is extracted from the gun.

Figure l is a side view of the gun. Fig. 2 is a vertical longitudinal section. Fig. 3 is a sectionalview of the bolt-head and extractor, retracting-tube, and iiringpin. Fig. 4 is a View of the rear end of the bolt and firing-pin. Fig. 5 is a front end view of the bolt with the bolt-head removed. Fig. 6 is a front end view of the bolt-head. Fig. 7 is a rear end view of the retracting-tube. Fig. 8 is an enlarged sectional view ot' Fig. 2.

Like letters designate corresponding parts in all the figures.

A, Figs. l and 2, is the stock of my improved re-arm, and B the barrel. H is the bolt. This bolt is made tubular, and is provided with a bolt-head, z. To this head I attach a combined lever and extractinghook, z". The said lever and hook are placed within a corresponding recess and mortise, m, the lever being pivoted between the centerand circumference of bolt-head, z, upon the side diametrically opposite to the point which' draws the shell.

The lever i is provided with an aperture corresponding with the center of the bolt-head, for the passage of the firing-pin. The rear of the bolt-head is provided with an extensiontube, which projects into the front end ot' the bolt H', where it is held in position by means p of a lng, a', projecting into the lateral groove u in said bolt.

This groove extends about one-half the distance around the inner circumference of the bore of said bolt, as shown by the dotted line, Fig. 5. In this view, u represents the end of a longitudinal groove, which connects with lateral groove u', the groove u being for the purpose of permitting a con nection to be formed between the bolt and its head.

The object oi the lateral groove is to allow the bolt H to rotate or rock while the head z remains idle, but movable therewith when said bolt is moved in a longitudinal direction.

The bolthead is kept from rotating by means of a lug, c, (shown projecting in Fig. 6,) which lugprojectsinto a longitudinal groove within the frame F. The lengt-h of this groove yequals the movement of said bolt-head.

The bore of the extensiontube in the rear of the bolt-head z extends to and unites with the mortise cc, for the purpose of receiving the retracting-tube t, provided with a head, s, which has a V-shaped notch formed therein.

One ofthe purposes for which the retractingtube is employed is to press against the combined lever and extraction hook t' and insure its contact with the cartridge-cases prior to their explosion but said hook is not dependent upon said tube for its contact with said cases while they are being extracted from` the chambers of the barrel, for the hold of the hook on said cartridges will be in proportion to the resistance offered by reason ofV the pivotal point around which the hook rotates being placed to one side of the draft ot' .said h ook and at a distance in the rear thereof. When, however, the shells are drawn from the chamber' of the barrel into the open chamber P this resistance ceases, and said shells would partially drop from the hook were it not for the pressure transmitted from the mainspring b through the retracting-tube c to said hook, whereby the shells are kept in contact with the side of the frame until the flange of the shells recedesintoarecessformedin said frame at the end of the backward movement of the bolt-head, thus causing the open end of the shell to fly out of the narrow opening P, while the base'thereof is ejected through the large opening P.

The tiring-pin e is provided with a V-projection formed on the head t, which fits into the Vnotch formed in the head of the reciprocating and non-rotating retraction-tube c. The parts t and s are brought together prior to the act of ring; but the tiring-pin is im- IOO mediately retracted when the boltH is rotated from its ring position, as shown in Fig. 2.

H is a hammer connected to tle firing-pin c, which is provided with a polygonal reciprocatin g bearing fitting into a corresponding aperture, g, in the rear end of the bolt H', said bearing and aperture being for the purpose of causing the iiring-pin to rotate with the holt. Theunder side of the bolt H is made ilat to a distance corresponding with the movement of said bolt. A shoulder, c', is formed on the bolt, which strikes against the stop f' when the bolt is withdrawn. About lone-fourth of the under side of the hammer is cut away for the purpose of permitting said hammer toro-y tate with the bolt H.

The spring I, Fig. 2, is shown depressed by the bolt-head z but when said bolt-head is sufficiently retracted the end of said spring will spring upward `on a line on a plane between the wide and narrow openings P and P, and

' within the alignment of the bore of the barr, formed ou guide tu,

rel B.

The object ot the spring is to prevent the cartridges from being thrown out of duealignment with the bore of the gun by preventing the cartridges entering the enlarged opening P', thus keeping' them adjacent to the narrow opening I? until forced into the chamber of its barrel B' by the action ot bolt H.

The frame F is recessed ath, as shown in Fig. 2, the object being to prevent an undue movement of the spring of the inclined cartridge-guide w when lug t' engages with the flanges of the cartridge. Said lug is brought in contact with said flange in its retrograde movement, and, in conjunction with shoulder causes the points of the cartridges to be elevated to the cavity h. In the meantime the elevated cartridge is underrun by the succeeding cartridge, which is bein g propelled from the magazineEby spring K.

When the elevated cartridge is to be forced into the chamber of the barrel, the bolt H is drawn back until lug t' is disengaged from the flange of the cartridge-case, after which the continued action of the7 magazine-spring will force the under-running cartridge up the inclined guide until its ange strikes the shoulder r. During this action the base ofthe elevated cartridge is brought in contact with stop-spring I and dropped into alignment, or nearly so, with the bore of the gun, into which it is forced by the reverse action ot' the bolt.

G and G represent a combined triggerguard and inclined cartridge-guide, which is preferably made in one piece; but said guard and guide can be made in parts and accomplish the same object.

The object of the inclined guide w is to bring the base of the cartridge to a point beneath bolt-head zj, so that when said bolt-head is drawn back the lug i will come in contact with the flange of said cartridges. In order to disengage the lug from said flange when the point of the cartridge is elevated to the frame at h, the inclined guide yields to the pressure transmitted from the bolt-head and lug through the cartridge-iiange until the depression of said guide is sufficient to admit ofthe passage of the lug over said flange.

The screws f, m, and J connect the combined trigger, guard, and guide G and Gr to the 'me F.

N represents the trigger, and y the triggerspring.

a is an aperture in the top of the frame, through which the cartridges are introduced when the .magazine is to be filled. Said aperture communicates or is cut into the side aperture I.

An unyielding guide, w, may be employed, in combination with a yielding lug, properly adjusted within the bolt-head z,- or a spring or its equivalent may be adj usted within the top of the frame at h.

` What I claim,and desire to secure by Letters Patent, is-

1. The inclined spring-guide w, provided` with a cartridgestop, r, in combination with the magazine located beneath the barrel B and the bolt-head z, with its lug fi, as and for the purpose herein speciied'.

2. The bolt-head z', with the lug` i, or its equivalent, and the inclined cartridge-guide w, provided with stop r, or its equivalent, in combination with the cartridge-magazine E and its spring, or its equivalent, for the purpose specih'ed.

3. In combination with a magazine fire-arm, a spring, I, located in the receiver in a position which will admit of its springing within alignment of the bore of said tire-arm, substantially as and for the purpose specified.

4. The pressure-tubev, iirin g-pin e, and mainspring b, in combination with the combinedlever and extractinghook fi and bolt-head z, for the purpose described.

5. The frame F, recessed at h, in combination with the shoulder r and lug t' and bolthead z, as and for the purpose described.
